> The achilles heal for sellers is that their listings ultimately need to show up When searching for unique information specific to a particular product. They’ll often try to hide that in an unrelated field or in the description. Usually a seller uses the same “trick” for all their listings.

By unique information, do you mean descriptive adjectives or product features? If so, these terms more often than not show up right in the title:

ProBien Case for iPhone 11, Liquid Silicone Phone Cover w Tempered Glass Screen Protector, Shockproof Durable Protective Rubber Cases Full Body Drop Protection 6.1 for Women Girls-Wine Red

60 Pack Guitar Picks,Cowalkers Abstract Art Random Color Celluloid Guitar Picks Plectrums Unique Guitar Gift For Electric, Bass & Acoustic Guitars Includes 0.46mm/0.71mm/0.96mm

COMFEE' Rice Cooker, Slow Cooker, Steamer, Stewpot, Sauté All in One (12 Digital Cooking Programs) Multi Cooker (5.2Qt ) Large Capacity. 24 Hours Preset & Instant Keep Warm

All of these items were on the first page of results for a single term (iphone 11 case, guitar pick, pressure cooker) so not only is Amazon failing to enforce TOS rules and guidelines against keyword-stuffing, the trick clearly works for sellers.
